Oh, wow. 8-O I can confirm the effect on my 3.2.3, but there seems to be
*more* of a problem with host freshness checks. Test run with
check_interval 15, retry_interval 2, max_check_attempts 4; log excerpt:

(The additional "no services" crud stems from my not getting the check
command right the first time 'round, and having to re-reload the config.)


I took excerpts of status.dat and retention.dat initially and after the
first nine active checks, look at these current_attempt numbers:


# for FIL in *.dat* ; do echo -n "${FIL}:  " | \
> sed -e 's/_[a-z]*-/-/' -e 's/\.[a-z]*: */:/' ; \
> egrep '(current_attempt|state_type|(current|last_hard)_state=)' \
> $FIL | sed -e 's/\([a-z][a-z][a-z]\)[a-z]*\([_=]\)/\1\2/g' | \
> tr '\n\t' '  ' ; echo "" ; done
retention.dat-OK:       cur_sta=0 las_har_sta=0 cur_att=1 sta_typ=1
retention.dat-1:        cur_sta=0 las_har_sta=0 cur_att=1 sta_typ=1
retention.dat-2:        cur_sta=1 las_har_sta=0 cur_att=1 sta_typ=0
retention.dat-3:        cur_sta=1 las_har_sta=0 cur_att=2 sta_typ=0
retention.dat-4:        cur_sta=1 las_har_sta=0 cur_att=2 sta_typ=0
retention.dat-5:        cur_sta=1 las_har_sta=0 cur_att=2 sta_typ=0
retention.dat-6:        cur_sta=1 las_har_sta=0 cur_att=4 sta_typ=1
retention.dat-7:        cur_sta=1 las_har_sta=0 cur_att=4 sta_typ=1
retention.dat-8:        cur_sta=1 las_har_sta=0 cur_att=4 sta_typ=1
retention.dat-9:        cur_sta=1 las_har_sta=0 cur_att=4 sta_typ=1
status.dat-OK:   cur_sta=0  las_har_sta=0  cur_att=1  sta_typ=1
status.dat-1:    cur_sta=1  las_har_sta=0  cur_att=1  sta_typ=0
status.dat-2:    cur_sta=1  las_har_sta=0  cur_att=2  sta_typ=0
status.dat-3:    cur_sta=1  las_har_sta=0  cur_att=2  sta_typ=0
status.dat-4:    cur_sta=1  las_har_sta=0  cur_att=3  sta_typ=0
status.dat-5:    cur_sta=1  las_har_sta=0  cur_att=4  sta_typ=1
status.dat-6:    cur_sta=1  las_har_sta=1  cur_att=1  sta_typ=1
status.dat-7:    cur_sta=1  las_har_sta=1  cur_att=1  sta_typ=1
status.dat-8:    cur_sta=1  las_har_sta=1  cur_att=1  sta_typ=1
status.dat-9:    cur_sta=1  las_har_sta=1  cur_att=1  sta_typ=1


extinfo.cgi told me "1/4 (SOFT state)" at 19:03 (after the *2nd* active
check, i.e., matching the data in retention.dat) but tells me "1/4 (HARD
state)" right now (matching status.dat instead) ...


Kind regards,
